BTW, as I haven't seen anyone comment on it yet, the SEC retroactively uploaded a bunch of CORRESP and UPLOAD filings going back to May for SCTY. Curiously, SCTY received comments on its 10-K, but I still haven't seen any comments on the S-4 (even though the SEC has approved it and they are clear to vote now).
Anyway, you can see what the SEC was focused on and how SCTY responded, which is always interesting. I haven't gotten all the way through it yet but there's definitely some interesting discussion about debt, MYPower loans, regulatory credits, etc. I recommend starting with the 6/8/16 CORRESP filing (which gives SCTY's responses to the SEC's initial comments) and follow the chain from there if you are so inclined.
